I love it when a product works out of the box, without requiring a lot of video tutorials or knowledge base article-reading. Pete's doing a great job with Contact Button and is terrific at communication if you do need an assist.

I bought Tier 2 and couldn't be happier. I've got 4 different links tied to one button -- an HTML embed, a reservation booking (TidyCal), an external link, and an internal page link. All work flawlessly, and the button's customization options are all you'd hope and expect from a product like this.
